Nursing Elites

1. Which of the following are key parameters that produce blood pressure? (Select ONE that does not apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Heart rate, stroke volume, and peripheral resistance are indeed key parameters that directly influence blood pressure. Heart rate refers to the number of times the heart beats per minute, affecting how much blood is pumped. Stroke volume is the amount of blood pumped by the heart in one contraction. Peripheral resistance is the resistance of the arteries to blood flow, impacting the pressure needed to push blood through. Neuroendocrine hormones, while they can indirectly influence blood pressure regulation by affecting factors like blood volume and vascular tone, are not direct final parameters that produce blood pressure.

2. A client with type 1 diabetes mellitus is learning to administer insulin. What is the best site for the nurse to recommend for insulin injection?

• A. Abdomen
• B. Thigh
• C. Upper arm
• D. Buttock

Correct answer: A

Rationale: The correct answer is the abdomen. The abdomen is the recommended site for insulin injection due to its faster absorption rate compared to other sites. Insulin injected into the abdomen is absorbed more quickly, leading to better glycemic control. The thigh and upper arm are also common sites for insulin injection, but they have slower absorption rates than the abdomen. The buttock is not a preferred site for insulin injection due to inconsistent absorption and potential risk of injecting into muscle instead of fatty tissue.

3. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure.
• B. Assess heart rate.
• C. Monitor respiratory rate.
• D. Measure oxygen saturation.

Correct answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

4. What is the most important action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter?

• A. Irrigate the catheter daily.
• B. Change the catheter every 72 hours.
• C. Apply antibiotic ointment at the insertion site.
• D. Ensure the catheter bag is always below bladder level.

Correct answer: D

Rationale: The most crucial action to prevent catheter-associated urinary tract infections (CAUTIs) in a client with an indwelling urinary catheter is to ensure that the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Irrigating the catheter daily (Choice A) is unnecessary and can introduce pathogens. Changing the catheter every 72 hours (Choice B) is not recommended unless clinically indicated to prevent introducing new pathogens. Applying antibiotic ointment at the insertion site (Choice C) is not the most important action to prevent CAUTIs; proper hygiene and maintaining a closed system are more critical.

5. The client with heart failure is prescribed furosemide (Lasix). What should the nurse include in the teaching plan?

• A. Increase potassium-rich foods in the diet
• B. Avoid foods high in sodium
• C. Monitor fluid intake and adjust as needed
• D. Take the medication in the morning

Correct answer: A

Rationale: The correct answer is to instruct the client to increase potassium-rich foods in the diet. Furosemide is a loop diuretic that can cause potassium loss as a side effect. By increasing potassium-rich foods, the client can help prevent hypokalemia, a potential complication of furosemide therapy. Choice B is incorrect because while limiting sodium intake is generally advisable for heart failure, it is not directly related to furosemide use. Choice C is incorrect because fluid intake should be monitored and adjusted based on the individual's condition, but setting a specific limit of 1 liter per day is not a standard recommendation. Choice D is incorrect because furosemide is usually taken in the morning to prevent disturbances in sleep due to increased urination during the night.
